Crown vetch, is not a true vetch, though it is a legume. It was or is commonly used by transportation departments to control erosion on banks and interchanges. Crown vetch is drought and cold hardy, disease resistant and seems to grow on the worst possible soils. However, this pink flowering perennial plant tends to become weedy, and allows a perfect habitat for burrowing animals, which isn't the best thing on banks. Plants don't respond to close mowings. Seeds should be sown at the rate of 1/2 to 3/4 pounds per 1000 square feet. 1994-dr
